What is Phosphonitrilic chloride?
a polymer composed mainly of hexachlorocyclotriphosphazotriene. Freshly produced phosphonitrilic chloride is an amorphous substance that partially crystallizes upon extension. Density, 2.4 g/cm3 at 20°C.
What type of structure does NPCl2 have?
The crystal structure of (NPCl2)3 is known to correspond to a planar conformation [1] while (NPCl2)4 exists in two different crystalline conformations [2,3], the S4 skew tub and the Ci skew chair forms, respectively.
What are polymeric backbone in silicones and phosphazenes?
The backbone is a chain of alternating silicon and oxygen atoms. Each silicone has two groups attached to it, and these can be any organic groups. The picture at the top of this page shows methyl groups attached to the silicon atoms. This polymer is called polydimethylsiloxane.
What are polymeric backbone in silicones and Phosphazenes?
What are Triphosphazenes?
A chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. The triphosphazene molecule contains a total of 9 bond(s) There are 4 non-H bond(s), 1 multiple bond(s), 1 rotatable bond(s) and 1 double bond(s).
What are the Phosphonitrilic compounds?
Phosphonitrilic chloride tri~ner, tetramer, and polymer have been studied by X-ray and electron diffraction (23-28). The trimer exists as an almost planar six- membered ring, the tetramer as a puckered eight-membered ring, and the polymer as a linear chain which is arranged in the form of a helix.
How Phosphonitrilic chloride is obtained?
Phosphonitrilic chloride trimer is ground in a mortar and pestle with ammonium persulfate in a ratio of 100 g of trimer to 2 g of persulfate (mole ratio = 2.87:0.0875, Note 1) to give an intimate mixture of the two compounds.

What is phosphazenes give one structure?
Phosphazenes, which are cyclic or linear chain inorganic compounds formed by the bonding and repetition of phosphorus and nitrogen atoms with (P=N)n bonds, comprise an important class of inorganic compounds (Figure 1). There are many phosphazene compounds ranging from oligomers to polymers.
What is silicone polymer?
A silicone polymer also known as polysiloxane is a type of polymer (inorganic polymer) that is mainly made up of polymerized siloxane (−R2Si−O−SiR2−). They are basically a type of synthetic polymer and are usually made up monomers that are bonded in long chains.

What is polymeric backbone in silicones and phosphazenes?
The backbone is a chain of alternating silicon and oxygen atoms. Each silicone has two groups attached to it, and these can be any organic groups. The picture at the top of this page shows methyl groups attached to the silicon atoms. This polymer is called polydimethylsiloxane. It is the most common silicone.
What is the structure of silicone?
The basic structure of silicone is made up of polyorganosiloxanes, where silicon atoms are linked to oxygen to create the «siloxane» bond. The remaining valences of silicon are linked to organic groups, mainly methyl groups (CH3): Phenyl, vinyl or hydrogen.
